前言
主要实现 Spring Security
的安全认证,结合 RESTful API
的风格,使用无状态的环境。
主要实现是通过请求的 URL ,通过过滤器来做不同的授权策略操作,为该请求提供某个认证的方法,然后进行认证,授权成功返回授权实例信息,供服务调用。
基于Token的身份验证的过程如下:
- 用户通过用户名和密码发送请求。
- 程序验证。
- 程序返回一个签名的token 给客户端。
- 客户端储存token,并且每次用于每次发送请求。
- 服务端验证token并返回数据。
每一次请求都需要token,所以每次请求都会去验证用户身份,所以这里必须要使用缓存,
基本使用
加入相关依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId>
</dependency>
了解基础配置
认证的基本信息
public interface UserDetails extends Serializable {//返回分配给用户的角色列表Collection<? extends GrantedAuthority> getAuthorities();//返回密码String getPassword();//返回帐号String getUsername();// 账户是否未过期boolean isAccountNonExpired();// 账户是否未锁定boolean isAccountNonLocked();// 密码是否未过期boolean isCredentialsNonExpired();// 账户是否激活boolean isEnabled();
}
获取基本信息
// 根据用户名查找用户的信息
public interface UserDetailsService {UserDetails loadUserByUsername(String username) throws UsernameNotFoundException;
}
我们只要实现这个扩展,就能够自定义方式获取认证的基本信息
WebSecurityConfigurerAdapter
WebSecurityConfigurerAdapter
提供了一种便利的方式去创建 WebSecurityConfigurer
的实例,只需要重写 WebSecurityConfigurerAdapter
的方法,即可配置拦截什么URL、设置什么权限等安全控制。
下面是主要会是要到的几个配置:
/*** 主要是对身份认证的设置* @param auth* @throws Exception*/ @Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {this.disableLocalConfigureAuthenticationBldr = true;}/*** 复写这个方法来配置 {@link HttpSecurity}. * 通常,子类不能通过调用 super 来调用此方法,因为它可能会覆盖其配置。 默认配置为:* */protected void configure(HttpSecurity http) throws Exception {logger.debug("Using default configure(HttpSecurity). If subclassed this will potentially override subclass configure(HttpSecurity).");http.authorizeRequests().anyRequest().authenticated().and().formLogin().and().httpBasic();}/*** Override this method to configure {@link WebSecurity}. For example, if you wish to* ignore certain requests.* 主要是对某些 web 静态资源的设置*/public void configure(WebSecurity web) throws Exception {}
认证流程
阅读源码了解。
AbstractAuthenticationProcessingFilter.doFilter
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)throws IOException, ServletException {HttpServletRequest request = (HttpServletRequest) req;HttpServletResponse response = (HttpServletResponse) res;// 判断是否是需要验证方法(是否是登陆的请求),不是的话直接放过if (!requiresAuthentication(request, response)) {chain.doFilter(request, response);return;}// 登陆的请求开始进行验证Authentication authResult;try {// 开始认证,attemptAuthentication在 UsernamePasswordAuthenticationFilter 中实现authResult = attemptAuthentication(request, response);// return null 认证失败if (authResult == null) {return;}// 篇幅问题,中间很多代码删了successfulAuthentication(request, response, chain, authResult);}
UsernamePasswordAuthenticationFilter.attemptAuthentication
// 接收并解析用户登陆信息,为已验证的用户返回一个已填充的身份验证令牌,表示成功的身份验证,
// 如果身份验证过程失败,就抛出一个AuthenticationException
public Authentication attemptAuthentication(HttpServletRequest request,HttpServletResponse response) throws AuthenticationException {if (postOnly && !request.getMethod().equals("POST")) {throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());}// 方法将 request 中的 username 和 password 生成 UsernamePasswordAuthenticationToken 对象,用于 AuthenticationManager 的验证String username = obtainUsername(request);String password = obtainPassword(request);if (username == null) {username = "";}if (password == null) {password = "";}username = username.trim();UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);// Allow subclasses to set the "details" propertysetDetails(request, authRequest);return this.getAuthenticationManager().authenticate(authRequest);}
ProviderManager.authenticate
验证 Authentication 对象(里面包含着验证对象)
- 如果有多个 AuthenticationProvider 支持验证传递过来的Authentication 对象,那么由第一个来确定结果,覆盖早期支持AuthenticationProviders 所引发的任何可能的AuthenticationException。 成功验证后,将不会尝试后续的AuthenticationProvider。
- 如果最后所有的 AuthenticationProviders 都没有成功验证 Authentication 对象,将抛出 AuthenticationException。
最后它调用的是 Authentication result = provider.authenticate(authentication);
只要我们自定义 AuthenticationProvider
就能完成自定义认证。

}
流程实现
认证流程:
JWT
我使用的是服务端无状态的token 交换的形式,所以引用的是 jwt,首先实现 jwt:
# jwt 配置
jwt:# 加密密钥secret: 61D73234C4F93E03074D74D74D1E39D9 #blog.wuwii.com# token有效时长expire: 7 # 7天,单位天# token 存在 header 中的参数header: token@ConfigurationProperties(prefix = "jwt")
@Data
public class JwtUtil {/*** 密钥*/private String secret;/*** 有效期限*/private int expire;/*** 存储 token*/private String header;/*** 生成jwt token** @param username* @return token*/public String generateToken(String username) {Date nowDate = new Date();return Jwts.builder().setHeaderParam("typ", "JWT")// 后续获取 subject 是 username.setSubject(username).setIssuedAt(nowDate).setExpiration(DateUtils.addDays(nowDate, expire))// 这里我采用的是 HS512 算法.signWith(SignatureAlgorithm.HS512, secret).compact();}/*** 解析 token,* 利用 jjwt 提供的parser传入秘钥,** @param token token* @return 数据声明 Map<String, Object>*/private Claims getClaimByToken(String token) {try {return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();} catch (Exception e) {return null;}}/*** token是否过期** @return true:过期*/public boolean isTokenExpired(Date expiration) {return expiration.before(new Date());}public String getUsernameFromToken(String token) {if (StringUtils.isBlank(token)) {throw new KCException("无效 token", HttpStatus.UNAUTHORIZED.value());}Claims claims = getClaimByToken(token);if (claims == null || isTokenExpired(claims.getExpiration())) {throw new KCException(header + "失效,请重新登录", HttpStatus.UNAUTHORIZED.value());}return claims.getSubject();}
}
实现 UserDetails 和 UserDetailsService
实现 UserDetails
public class UserDetailsImpl implements UserDetails {private User user;public UserDetailsImpl(User user) {this.user = user;}/*** 获取权限信息* @return*/@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {Set<UserRole> userRoles = user.getUserRoles();List<GrantedAuthority> auths = new ArrayList<>(userRoles.size());userRoles.parallelStream().forEach(userRole -> {// 默认ROLE_ 为前缀,可以更改auths.add(new SimpleGrantedAuthority("ROLE_" + userRole.getRole().getName()));});return auths;}@Overridepublic String getPassword() {return user.getPassword();}@Overridepublic String getUsername() {return user.getUsername();}// 账户是否未过期@JsonIgnore@Overridepublic boolean isAccountNonExpired() {return true;}// 账户是否未锁定@JsonIgnore@Overridepublic boolean isAccountNonLocked() {return true;}// 密码是否未过期@JsonIgnore@Overridepublic boolean isCredentialsNonExpired() {return true;}// 账户是否激活@JsonIgnore@Overridepublic boolean isEnabled() {return true;}
}
实现 UserDetailsService
@Slf4j
@CacheConfig(cacheNames = "users")
public class UserDetailServiceImpl implements UserDetailsService {@Autowiredprivate UserDao userDao;@Override@Cacheablepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {User user = userDao.findByUsername(username);if (user == null) {throw new UsernameNotFoundException("Username is not valid.");}log.debug("The User is {}", user);return SecurityModelFactory.create(user);}
}
SecurityModelFactory
转换 UserDetails 的工厂类
public class SecurityModelFactory {public static UserDetails create(User user) {return new UserDetailsImpl(user);}
}
授权认证
登陆过滤器
public class LoginFilter extends UsernamePasswordAuthenticationFilter {@Autowiredprivate JwtUtil jwtUtil;/*** 过滤,我目前使用的是默认的,可以自己看源码按需求更改*/@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {// todo 在这里可以按需求进行过滤,根据源码来修改扩展非常方便super.doFilter(request, response, chain);}/*** 如果需要进行登陆认证,会在这里进行预处理*/@Overridepublic Authentication attemptAuthentication(HttpServletRequest request,HttpServletResponse response) throws AuthenticationException {// todo 在登陆认证的时候,可以做些其他的验证操作,比如验证码return super.attemptAuthentication(request, response);}/*** 登陆成功调用,返回 token*/@Overrideprotected void successfulAuthentication(HttpServletRequest request,HttpServletResponse response,FilterChain chain, Authentication authResult) throws IOException {String token = jwtUtil.generateToken(authResult.getName());response.setStatus(HttpStatus.OK.value());response.getWriter().print(token);}
}
- 首先会进入
doFilter
方法中,这里可以自定义定义过滤; - 然后如果是
登陆
的请求,会进入attemptAuthentication
组装登陆信息,并且进行登陆认证; - 如果登陆成功,会调用
successfulAuthentication
方法。
登陆验证
@Slf4j
public class CustomAuthenticationProvider implements AuthenticationProvider {@Autowiredprivate UserDetailsService userDetailsService;@Autowiredprivate PasswordEncoder passwordEncoder;/*** 验证登录信息,若登陆成功,设置 Authentication*/@Overridepublic Authentication authenticate(Authentication authentication) throws AuthenticationException {String username = authentication.getName();String password = (String) authentication.getCredentials();UserDetails user = userDetailsService.loadUserByUsername(username);if (passwordEncoder.matches(password, user.getPassword())) {Collection<? extends GrantedAuthority> authorities = user.getAuthorities();return new UsernamePasswordAuthenticationToken(username, password, authorities);}throw new BadCredentialsException("The password is not correct.");}/*** 当前 Provider 是否支持对该类型的凭证提供认证服务*/@Overridepublic boolean supports(Class<?> authentication) {return UsernamePasswordAuthenticationToken.class.equals(authentication);}
}
我们自己定义的 AuthenticationProvider
主要是实现前面经过过滤器封装的认证对象 UsernamePasswordAuthenticationToken
进行解析认证,
如果认证成功 就给改 UsernamePasswordAuthenticationToken
设置对应的权限,然后返回 Authentication
- 获得认证的信息;
- 去数据库查询信息,获取密码解密验证认证信息;
- 认证成功,设置权限信息,返回
Authentication
,失败抛出异常。
JWT 拦截器
/*** token 校验* BasicAuthenticationFilter 滤器负责处理任何具有HTTP请求头的请求的请求,* 以及一个基本的身份验证方案和一个base64编码的用户名:密码令牌。*/
public class JwtAuthenticationFilter extends BasicAuthenticationFilter {@Autowiredprivate JwtUtil jwtUtil;@Autowiredprivate UserDetailsService userDetailsService;public JwtAuthenticationFilter(AuthenticationManager authenticationManager) {super(authenticationManager);}/*** 在此方法中检验客户端请求头中的token,* 如果存在并合法,就把token中的信息封装到 Authentication 类型的对象中,* 最后使用 SecurityContextHolder.getContext().setAuthentication(authentication); 改变或删除当前已经验证的 pricipal** @param request* @param response* @param chain* @throws IOException* @throws ServletException*/@Overrideprotected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {String token = request.getHeader(jwtUtil.getHeader());//判断是否有tokenif (token == null) {chain.doFilter(request, response);return;}// 通过token 获取账户信息,并且存入到将身份信息存放在安全系统的上下文。UsernamePasswordAuthenticationToken authenticationToken = getAuthentication(token);SecurityContextHolder.getContext().setAuthentication(authenticationToken);//放行chain.doFilter(request, response);}/*** 解析token中的信息*/private UsernamePasswordAuthenticationToken getAuthentication(String token) {String username = jwtUtil.getUsernameFromToken(token);UserDetails userDetails = userDetailsService.loadUserByUsername(username);if (username != null) {return new UsernamePasswordAuthenticationToken(username, null, userDetails.getAuthorities());}return null;}
}
- 请求进入
doFilterInternal
方法中,对请求是否带token
进行判断, - 如果没有token,则直接放行请求;
- 如果有 token,则解析它的 post;
配置权限和相关设置
自定义配置 Spring Security 配置类 WebSecurityConfig
,进项相关配置,并且将所需要的类注入到系统中。
@Configuration
@EnableWebSecurity // 开启 Security
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
//jsr250Enabled有三种注解,分别是@RolesAllowed,@PermitAll,@DenyAll,功能跟名字一样,
// securedEnabled 开启注解
// prePostEnabled 类似用的最多的是 @PreAuthorize
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Beanpublic JwtUtil jwtUtil() {return new JwtUtil();}/*** 注入 LoginFilter 时候需要,注入 authenticationManager*/@Beanpublic LoginFilter loginFilter() throws Exception {LoginFilter loginFilter = new LoginFilter();loginFilter.setAuthenticationManager(authenticationManager());return loginFilter;}@Beanpublic JwtAuthenticationFilter jwtAuthenticationFilter() throws Exception {return new JwtAuthenticationFilter(authenticationManager());}@Beanpublic UserDetailsService customService() {return new UserDetailServiceImpl();}/*** 认证 AuthenticationProvider*/@Beanpublic AuthenticationProvider authenticationProvider() {return new CustomAuthenticationProvider();}/*** BCrypt算法免除存储salt* BCrypt算法将salt随机并混入最终加密后的密码,验证时也无需单独提供之前的salt,从而无需单独处理salt问题。* @return*/@Beanpublic PasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder(5);}/*** 主要是对身份验证的设置*/@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth// 注入身份的 Bean.authenticationProvider(authenticationProvider()).userDetailsService(userDetailsService())// 默认登陆的加密,自定义登陆的时候无效.passwordEncoder(passwordEncoder());// 在内存中设置固定的账户密码以及身份信息/*auth.inMemoryAuthentication().withUser("user").password("password").roles("USER").and().withUser("admin").password("password").roles("USER", "ADMIN");*/}/**** @param http* @throws Exception*/@Overrideprotected void configure(HttpSecurity http) throws Exception {http// 关闭 csrf.csrf().disable()// 设置 session 状态 STATELESS 无状态.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().authorizeRequests()// 需要权限验证.mvcMatchers("/user/**").authenticated().and()// 登陆页面.formLogin()//.loginPage("/login.html")// 登陆成功跳转页面.defaultSuccessUrl("/")//.failureForwardUrl("/login.html").permitAll().and()// 登出//.logout()// 注销的时候删除会话//.deleteCookies("JSESSIONID")// 默认登出请求为 /logout,可以用下面自定义//.logoutRequestMatcher(new AntPathRequestMatcher("/logout"))// 自定义登出成功的页面,默认为登陆页//.logoutSuccessUrl("/logout.html")//.permitAll()//.and()// 开启 cookie 保存用户信息//.rememberMe()// cookie 有效时间//.tokenValiditySeconds(60 * 60 * 24 * 7)// 设置cookie 的私钥,默认为随机生成的key//.key("remember")//.and()//验证登陆的 filter.addFilter(loginFilter())//验证token的 filter.addFilter(jwtAuthenticationFilter());}/*** Web层面的配置,一般用来配置无需安全检查的路径* @param web* @throws Exception*/@Overridepublic void configure(WebSecurity web) throws Exception {web.ignoring().antMatchers("**.js","**.css","/images/**","/webjars/**","/**/favicon.ico");}
}
权限控制
@RestController
@RequestMapping(value = "/user", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
@PreAuthorize("hasRole('USER')")
public class UserController {@Autowiredprivate UserService userService;@GetMapping@PreAuthorize("hasRole('admin')")public ResponseEntity<List<UserVO>> getAllUser() {List<User> users = userService.findAll();List<UserVO> userViews = userService.castUserVO(users);return ResponseEntity.ok(userViews);}
}
请求上面的getAllUser
方法,需要当前用户同时拥有 ROLE_USER
和 ROLE_admin
两个权限,才能通过权限验证。
在 @PreAuthorize 中我们可以利用内建的 SPEL 表达式:比如 ‘hasRole()’ 来决定哪些用户有权访问。需注意的一点是 hasRole 表达式认为每个角色名字前都有一个前缀 ‘ROLE_’。
迭代上个版本
后来,我发现进行用户认证的时候,会将所有的 provider 都尝试一遍,那么外面将登陆的 UsernameAndPasswordToken
和 JwtTToken
都可以分别进行验证进行了啊,所有我预先定义 UsernamePasswordAuthenticationToken
包装登陆的信息,然后进入登陆的 AuthenticationProvider
进行认证,token
验证形式,使用 PreAuthenticatedAuthenticationToken
的包装,然后进入例外一个 AuthenticationProvider
中认证。
现在我们的流程就更加清晰了。
所以现在我对以前的权限配置以及认证进行了一些更改:
过滤器
在这里,我根据不同请求的类型,进行不同的适配,然后进行加工分装成不同的认证凭证,然后根据凭证的不同,进行不同的认证。
@Slf4j
public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter {@Autowiredprivate JwtUtil jwtUtil;@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {HttpServletRequest httpRequest = (HttpServletRequest) request;HttpServletResponse httpResponse = (HttpServletResponse) response;try {if (isLoginRequest(httpRequest, httpResponse)) {Authentication authResult = processLogin(httpRequest, httpResponse);successfulAuthentication(httpRequest, httpResponse, chain, authResult);return;}String token = obtainToken(httpRequest);if (StringUtils.isNotBlank(token)) {processTokenAuthentication(token);}} catch (AuthenticationException e) {unsuccessfulAuthentication(httpRequest, httpResponse, e);return;}chain.doFilter(request, response);}/*** 登陆成功调用,返回 token*/@Overrideprotected void successfulAuthentication(HttpServletRequest request,HttpServletResponse response,FilterChain chain, Authentication authResult) throws IOException {String token = jwtUtil.generateToken(authResult.getName());response.setStatus(HttpStatus.OK.value());response.getWriter().print(token);}private boolean isLoginRequest(HttpServletRequest request, HttpServletResponse response) {return requiresAuthentication(request, response) && "POST".equalsIgnoreCase(request.getMethod());}private String obtainToken(HttpServletRequest request) {return request.getHeader(jwtUtil.getHeader());}private Authentication processLogin(HttpServletRequest request, HttpServletResponse response) {String username = obtainUsername(request);String password = obtainPassword(request);return tryAuthenticationWithUsernameAndPassword(username, password);}private void processTokenAuthentication(String token) {Authentication resultOfAuthentication = tryToAuthenticateWithToken(token);// 设置上下文用户信息以及权限SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);}private Authentication tryAuthenticationWithUsernameAndPassword(String username, String password) {Authentication authentication = new UsernamePasswordAuthenticationToken(username, password);return tryToAuthenticate(authentication);}private Authentication tryToAuthenticateWithToken(String token) {PreAuthenticatedAuthenticationToken requestAuthentication = new PreAuthenticatedAuthenticationToken(token, null);return tryToAuthenticate(requestAuthentication);}private Authentication tryToAuthenticate(Authentication requestAuth) {Authentication responseAuth = getAuthenticationManager().authenticate(requestAuth);if (responseAuth == null || !responseAuth.isAuthenticated()) {throw new InternalAuthenticationServiceException("Unable to authenticate User for provided credentials");}log.debug("User successfully authenticated");return responseAuth;}
}
授权认证
根据提供的凭证的类型,进行相关的验证操作
LoginAuthenticationProvider
跟上个版本的 登陆验证中的 CustomAuthenticationProvider
代码一样实现一样。
TokenAuthenticateProvider
根据 token 查找它的 权限 信息,并装在到认证的凭证中。
public class TokenAuthenticateProvider implements AuthenticationProvider {@Autowiredprivate JwtUtil jwtUtil;@Autowiredprivate UserDetailsService userDetailsService;@Overridepublic Authentication authenticate(Authentication authentication) throws AuthenticationException {String token = authentication.getName();String username = jwtUtil.getUsernameFromToken(token);UserDetails userDetails = userDetailsService.loadUserByUsername(username);return new PreAuthenticatedAuthenticationToken(username, null, userDetails.getAuthorities());}@Overridepublic boolean supports(Class<?> authentication) {return PreAuthenticatedAuthenticationToken.class.equals(authentication);}
}
配置权限和相关设置
和上个版本没什么变化,只是将类换了一下
@Configuration
@EnableWebSecurity // 开启 Security
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Beanpublic JwtUtil jwtUtil() {return new JwtUtil();}@Beanpublic UserDetailsService customService() {return new UserDetailServiceImpl();}@Bean("loginAuthenticationProvider")public AuthenticationProvider loginAuthenticationProvider() {return new LoginAuthenticationProvider();}@Bean("tokenAuthenticationProvider")public AuthenticationProvider tokenAuthenticationProvider() {return new TokenAuthenticateProvider();}@Beanpublic AuthenticationFilter authenticationFilter() throws Exception {AuthenticationFilter authenticationFilter = new AuthenticationFilter();authenticationFilter.setAuthenticationManager(authenticationManager());return authenticationFilter;}@Beanpublic PasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder(5);}@Bean@Overridepublic UserDetailsService userDetailsService() {return new UserDetailServiceImpl();}/*** 主要是对身份验证的设置*/@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.authenticationProvider(loginAuthenticationProvider()).authenticationProvider(tokenAuthenticationProvider()).userDetailsService(userDetailsService());}@Overrideprotected void configure(HttpSecurity http) throws Exception {http// 关闭 csrf.csrf().disable()// 设置 session 状态 STATELESS 无状态.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().authorizeRequests()// 需要权限验证.mvcMatchers("/user/**").authenticated().and()// 登陆页面.formLogin()//.loginPage("/login.html")// 登陆成功跳转页面.defaultSuccessUrl("/").failureForwardUrl("/login.html").permitAll().and().addFilter(authenticationFilter());}
}
后续完善
- 修改密码,登出操作 token 的失效机制;
- OAuth2 授权服务器的搭建;
- 修改权限后,下次请求刷新权限;
- ……
